Usain Bolt plans to defend his Olympic titles in 2016...

Usain Bolt announced today that he plans to defend his Olympic 100m and 200m sprint titles at the 2016 Rio de Janeiro Games. The Jamaican, who retained both titles as well as the 4x100m in London, said he has decided against switching to either the 400m or long jump.

In an interview, the 26 year old Bolt said...."To do the three [sprints], that is the focus. I don't want to try any different events at Rio. I will just defend my titles to show the world there's a possibility I can do it again."
